A gas laser generator uses a mixed gas such as He,
When glow discharge is performed in an excitation space containing N 2 , CO 2 , etc., the mixed gas is excited and laser light is generated. The laser beam resonates between a plurality of mirrors provided in the excitation space, is extracted to the outside through an output mirror, and is used to cut iron plates, ceramics, etc. Narrower cutting widths can be applied to precision machining, allowing for a wider range of product applications. Laser light that satisfies this condition is generally referred to as having single mode characteristics. The single mode characteristic is a characteristic in which the energy density at the center of the laser beam is significantly higher than at the outer periphery. To obtain single-mode characteristics, in order to extend the resonance length of the laser beam, folding mirrors are installed at both ends of the excitation space, and the laser beam is sent back and forth between the folding mirrors many times, or the optical axis of the laser beam is Adjust multiple mirror positions so that they are centered,
However, there was a limit to the ability to obtain a laser beam with high power density.

As a result of examining the output laser beam, it was found that the output laser beam has a beam waist where the laser beam is focused at a certain distance, the spot diameter is small, and the power density is high. A cutting head is installed to enable processing with a narrow cutting width.

（α′←→β′）方向に移動できる。 As shown in the figure, the output side of the laser generator 2 and the processing table 3 are arranged in correspondence with each other with a space in between. There are two sets of rails 4 on the top surface of the processing table 3.
is installed. The rail 4 is arranged in a direction perpendicular to the laser beam 1A from the laser generator 2. The rail 4 accommodates welding and cutting heads 5, 6. Processing head 7 for heat treatment
is fixed on the processing table. These processing heads 5, 6, and 7 each form a hole 8 on the corresponding surface on the laser generator side and an inclined surface 9 on the opposite side to the hole 8, and the bottom surfaces of the processing heads 5, 6 for welding and cutting. A box body 11 is constructed by attaching a guide 10 to be fitted into the rail 4. The bend mirror 12 shown in FIG. 2 attached to the inclined surface 9 irradiates the laser beam 1A from the laser generator 2, and irradiates the condenser lens 13 in the right angle direction. The condensing lens 13 and the box body 10 are communicated by pipes 14A, B, and the condensing lens 13 is supported by the pipes 14A, 14B. The pipe 14A, like the welding and cutting heads 5, 6, can be moved in the (α←→β) direction via the rail 4. The laser beam 1A transmitted through the condenser lens 13 irradiates the workpiece 15, for example, an iron plate, and cuts the iron plate.
A workpiece 15 is placed on the moving table 16 on the upper side, and a guide 17 is attached on the lower side, and the guide 17 is fitted into a rail 18 extending in the same direction as the laser beam 1A. Therefore, the moving table 16 can move in the (α'←→β') direction.

適用できる。 With this configuration, the laser beam 1A resonates between the total reflection mirror 2A and the output mirror 2B of the laser generator 2,
The light is irradiated to the outside from the output mirror 2B. When this laser beam 1A is measured with an acrylic burn pattern or a beam diameter concentrator, the laser beam 1A is focused, as shown in FIGS. 3 and 4, and has a small spot diameter and a high power density energy. It has a beam waist 1B. In the present invention, the cutting head 6 is connected to the beam waist 1B.
It is located in As a result, a laser beam with high power density and energy can be used.
The cutting width can be made smaller when cutting the workpiece 15 depending on the beam mode. Therefore, it can be applied to a wide range of applications from rough cutting to precision cutting when cutting workpieces.

ができる。 On the other hand, if the cutting head 6 is placed between the welding head 5 and the heat treatment head 7,
For example, when cutting a long steel plate from the middle to form short steel plates of the same size, the center of the steel plate fixed to the moving table 16 is placed under the cutting head 6. In this case, the steel plate extends an equal distance from the corresponding location of the cutting head 6 toward the welding head 5 and the heat treatment head 7, so that the steel plate does not require much space.
For example, if the processing head for cutting is located at the location of the processing head for welding, when the steel plate is arranged as in the above situation, the steel plate will protrude to one side, requiring more space to install the steel plate. However, this can be prevented by the configuration of this embodiment. Also, when welding or heat treating cut steel plates,
Since the moving distance for moving the cut steel plate from the cutting processing head 6 to the welding processing head 5 or the heat treatment processing head 7 is short, work efficiency can be improved.

の熱処理を容易に行うことができる。 Furthermore, by arranging the welding processing head 5 on the laser generator side of the cutting processing head 6 and the heat treatment processing head 7 on the opposite side as shown in FIG. 1, the following effects can be achieved. That is, as shown in FIGS. 3 and 4, the diameter of the laser beam 1C on the laser generator side of the beam waist 1B is smaller than the laser beam diameter 1D on the other side. That is, since the divergence angle of the laser beam 1D is wider than that of the laser beam 1C, the spot diameter of the heat treatment processing head 7 can be made larger than the spot diameter of the welding and cutting processing heads 5, 6. Therefore, heat treatment over a wide area can be easily performed.

と共に、小型化できる。 Furthermore, as shown in Fig. 4, if a convex lens is used for the output mirror 2B, the diameter of the laser beam from the laser oscillator 2 can be made narrower, so that, for example, when the laser beam is mainly used for cutting, the beam condensing diameter can be made narrower. . In addition, even in the case of welding and heat treatment, since the beam becomes narrower, the lenses, mirrors, and holders can be made smaller, which has the effect of allowing the size to be adjusted according to needs, and the size can be reduced.

According to the laser processing machine of the present invention explained above,
Since the processing head for cutting is arranged at the waist point of the laser beam, processing can be performed using a laser beam with high power density, so it is possible to obtain this type of laser processing machine that can perform processing with a narrow cutting width.
